Introduction: Anti-vaccination movements exist in Europe and it may reduce adherence to international vaccination.Objectives:To evaluate attitudes on vaccination among Portuguese travelers and Brazilian migrants in Portugal.Material and Methods:Between May and June 2019 a cross-sectional survey was carried out in the Travel Clinic of the Institute of Hygiene and Tropical Medicine of Lisbon. A self-administered questionnaire was applied after medical consultation. Travelers were asked about their attitudes to vaccines. An anonymous web-based survey was sent to Brazilian migrants living in Portugal for at least 6 months.Results: 55 Portuguese (P) travelers and 22 Brazilian (B) migrants answered the questionnaire. 47.3% of Portuguese travelers were male; the mean age was 33 years; reason for travel: tourism (43.6%) or business (30.9%). 31.8% of Brazilian migrants were male and the mean age was 44 years; 71.4% were living in Portugal for ≤ 2 years. Attitudes towards vaccines: 64.8% P and 68.2% B prefer to vaccine even when the risk of acquire a disease is low; 64.1% P and 95.5% B consider that the resistance acquired by disease is better than resistance acquired by vaccine; 75.5% P and 77.3% B prefer to vaccine even when diseases are not severe; 5.6% P and 13.6% B don’t take vaccines because they are afraid of side effects.About the reasons to accept a vaccine, travelers/migrants consider very important to trust in the doctor (100% P, 95.4% B), and the excellent protective effect of a vaccine (98.1% P, 90.9% B).Conclusions: Portuguese travelers and Brazilian migrants in Portugal seem to have a favorable attitude towards vaccination, despite the anti-vaccination movements in Europe. They believe that trust in the doctor and excellent protection of the vaccines are reasons to accept it. The quality of traveler's advice may maintain/increase adherence to vaccination.

Background: Hip resurfacing arthroplasty (HRA) typically uses a hybrid design (cemented femoral component and cementless acetabular shell) but has recently been performed with fully cementless components. There is a paucity of information on the clinical performance of these cementless designs. Methods: The UCLA clinical scores, SF-12 quality of life scores, complication rates, survivorship and radiographic signs of loosening or gross stress shielding of 39 hips (39 male patients) implanted with cementless HRA were compared with those of 40 hips (37 male patients) implanted with hybrid HRA during the same time frame. Results: There were no significant differences in postoperative clinical and quality of life scores, complication rates, or radiographic signs of loosening between the 2 groups. The 5-year Kaplan-Meier survivorship was 97.2% for the cementless group and 100% for the hybrid group. This difference was not significant ( p = 0.3694). There were no femoral component failures in any of the 2 groups. Conclusions: At a mean follow-up of 6 years, there is no tangible difference between the performance of cementless HRA compared to hybrid HRA. The absence of learning curve associated with this device and the potential for better preservation of femoral neck bone mineral density suggest that this technology is well suited for young patients with good bone quality seeking to resume an active lifestyle including high-impact activities.

Rate Of Failure

Hip resurfacing arthroplasty is an very interesting and controversial orthopedic concept in the last years [1]. In order to avoid the previous problems associated with the classical hip prosthesis type metal-polyethylene [2], different manufacturer propose the metal-metal prosthesis based on the reproducible quality of manufacturing of metallic components using Co-Cr alloys and better component fixation. Problems that have been encountered to be the reason for failing of the prosthesis can be different (dislocation, femoral neck fractures, vascular damage, avascular necrosis, raised metal ion levels), and could be related to three main aspects: factors related to the patients, surgical intervention and prosthesis [3, 4]. But a very important aspect is the biomaterials used, that will be discussed in the present paper in correlation with biomechanics and clinical aspects. Our study maked on a lot of retrieved BHR prosthesis used in one Romanian orthopaedic clinic present a higher rate of failure than the other similar studies made by other authors [5]. Starting from this point, we analyze carefully many components of the failed BHR prosthesis using stereomicroscopy, scanning electron microscopy (SEM) and EDS. Based on our experimental results especially at the interfaces metal-cement-bone, we identify different potential causes of failure but the main conclusion was that the cementation technique and poor quality of the patient bone are the reasons for most of hip resurfacing prosthesis failure. As future recommendations for the orthopaedic surgeons we could mention the carefully analysis of bone quality for each candidate using advanced techniques like DEXA and a correlation between the bone cement used for prosthesis fixation and the cementation technique.

Hip resurfacing arthroplasty is known to improve quality of life (QoL) and allow increased activity levels in young patients. It is, however, traditionally offered to the younger age group of patients, largely those aged under 60 years. We studied 42 consecutive patients (42 hips) aged 60 years or over (mean age 64) and 41 consecutive patients (42 hips) under this age (mean age 49), all of whom had undergone a metal-on-metal hip resurfacing arthroplasty. A modified Harris hip score was translated to QoL scores using the Rosser Index Matrix immediately pre-operatively and at six weeks, six months, one year and four years after surgery. We found a significant improvement in QoL for both groups (p<0.0001) but no difference between the two groups. The maximum improvement was reached one year after surgery. Implant survival at four years was also similar (97.6% for group I and 100% for group II). We thus conclude that in carefully selected active patients aged 60 years and over, hip resurfacing arthroplasty provides significant and equal QoL improvement as it does for those under this age with similar implant survival. For this reason, age alone should not influence a surgeon's decision to proceed with a hip resurfacing arthroplasty.

Dengue fever is one of the most important viral infections transmitted by Aedes mosquitoes and a major cause of morbidity and mortality globally. Accurate identification of cases and treatment of dengue patients at the early stages can reduce medical complications and dengue mortality rate. This survey aims to determine the knowledge, attitude, and practices (KAP) among physicians in dengue diagnosis and treatment. This study was conducted among physicians in Turkey as one nonendemic country and Bangladesh, India, and Malaysia as three dengue-endemic countries. The dosing frequencies, maximum doses, and contraindications in dengue fever were examined. The results found that physicians from Bangladesh, India, and Malaysia have higher KAP scores in dengue diagnosis and treatment compared to physicians in Turkey. This may be due to a lack of physician’s exposure to a dengue patient as Turkey is considered a nonendemic country. This assessment may help establish a guideline for intervention strategies among physicians to have successful treatment outcomes and reduce dengue mortality.
